curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = explode("\r\n\r\nHTTP/", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = explode("\r\n\r\n", $parts, 2);

适用于HTTP/1.1 100在其他报头之前继续。

如果你需要使用错误服务器，只发送LF而不是CRLF作为换行符，你可以使用preg_split，如下所示:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = preg_split("@\r?\n\r?\nHTTP/@u", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = preg_split("@\r?\n\r?\n@u", $parts, 2);

杰弗里回答的改进:

我不能得到正确的长度头部与$headerSize = curl_getinfo($this->curlHandler, CURLINFO_HEADER_SIZE);-我必须计算头部大小我自己。

此外，为了提高可读性，还做了一些改进。

$headerSize = 0;
curl_setopt_array($this->curlHandler, [
CURLOPT_URL => $yourUrl,
CURLOPT_POST => 0,
CURLOPT_RETURNTRANSFER => 1,
// this function is called by curl for each header received
CURLOPT_HEADERFUNCTION =>
         function ($curl, $header) use (&$headers, &$headerSize) {
              $lenghtCurrentLine = strlen($header);
              $headerSize += $lenghtCurrentLine;
              $header = explode(':', $header, 2);
              if (count($header) > 1) { // store only vadid headers
                   $headers[strtolower(trim($header[0]))][] = trim($header[1]);
              }
              return $lenghtCurrentLine;
           },
]);
$fullResult = curl_exec($this->curlHandler);
$result = substr($fullResult, $headerSize);

只需设置选项:

CURLOPT_HEADER, 0岁 CURLOPT_RETURNTRANSFER, 1

并使用curl_getinfo与CURLINFO_HTTP_CODE(或没有opt参数，你将有一个与所有你想要的信息的关联数组)

更多信息请访问:http://php.net/manual/fr/function.curl-getinfo.php

如果你特别想要Content-Type，有一个特殊的cURL选项来检索它:

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$content_type = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);

以防你不能/不使用CURLOPT_HEADERFUNCTION或其他解决方案;

$nextCheck = function($body) {
    return ($body && strpos($body, 'HTTP/') === 0);
};

[$headers, $body] = explode("\r\n\r\n", $result, 2);
if ($nextCheck($body)) {
    do {
        [$headers, $body] = explode("\r\n\r\n", $body, 2);
    } while ($nextCheck($body));
}

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = explode("\r\n\r\nHTTP/", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = explode("\r\n\r\n", $parts, 2);
